What is Java?
Java is a widely used programming language expressly designed for use in the distributed environment of the internet. It is the most popular programming language for Android smartphone applications and is also among the most favored for the development of edge devices and the internet of things.Java was designed to have the look and feel of the C++ programming language, but is simpler to use and enforces an object-oriented programming model.
Benefits Of Java
- Programs created in Java offer portability in a network. Source code is compiled into what Java calls bytecode, which can run anywhere in a network, on a server or on a client that has a Java virtual machine (JVM). The JVM interprets the bytecode into code that will run on computer hardware.
- Java is object-oriented. An object is made up of data as fields or attributes and code as procedures or methods. An object can be a part of a class of objects to inherit code common to the class
- The code is robust. Unlike programs written in C++, Java objects contain no references to data external to themselves or other known objects.
- Data is secure. Unlike C++, Java does not use pointers, which can be unsecured. Data converted to bytecode by Java is also not readable to humans. Additionally, Java will run programs inside a sandbox to prevent changes from unknown sources..
- Applets offer flexibility. In addition to being executed on the client rather than the server, a Java applet has other characteristics designed to make it run fast.
